Opening structure for ventilation device {Structure for opening and closing for ventilator}

The present invention relates to an opening and closing structure for a ventilation device, and more particularly to a ventilation structure opening and closing structure, the structure can be improved so that the user can adjust the flow rate of the outdoor unit introduced during opening, while being able to obtain a sense of control with a simple structure. will be.

In general, the role of the window is to act as a mining role to receive light and to ventilate the indoor and outdoor air by opening and closing the window.

Contaminated indoor air causes many diseases in the human body, and in particular, various dusts and microorganisms in the contaminated air cause respiratory diseases and allergies, and various pollutants (formaldehyde, volatile organic substances) emitted from indoor building materials. , Asbestos powder) causes diseases such as headache, cough and itching.

Therefore, it is preferable to ventilate the interior and exterior to frequently ventilate the air so that various contaminants do not accumulate in the interior.

By the way, the conventional window has a problem that a strong wind flows in the case of opening the window to ventilate or the rain water or dust from the outside is introduced into the room.

In addition, in the case of existing windows, air containing soot flows directly into the room in the process of simply entering the outside air, thereby not only losing the function of the ventilation itself, but worsening than the indoor air. There was a risk of air inflow.

In order to solve this problem, Utility Model Registration No. 20-216482 forms a ventilating hole before and after the window frame, and inside the ventilating connecting the front plate having a small pore set in front and the rear plate having a hole in the rear with a spacer. There is one configured to control the opening and closing of the front and rear ventilation holes of the frame while slidingly adjusting the control.

And, the front of the window frame is provided with a ventilation cover.

The ventilation device is to adjust the ventilation amount according to the degree of engagement of the small holes of the front plate and the hole of the rear plate with the window frame while sliding the ventilation control in the lateral direction.

However, the existing ventilation device is provided directly on the window frame, there is a problem that its installation is difficult, such as a general window or other door, wall surface.

In addition, since the ventilation device of the window frame, the small holes of the front panel, the holes of the rear panel are formed horizontally to allow the air to enter and exit horizontally, it is easy to introduce external rainwater, dust or strong wind. there was.

In addition, the ventilation device is inconvenient to move the entire ventilation control unit combining the front panel and the rear panel with a spacer when adjusting the ventilation amount, and the movement of the ventilation control unit must be kept in a spaced state without being in close contact with the window frame to move the ventilation control unit. Even if the sphere is closed, there is a problem that can be the cause of heat loss in winter by the generation of gaps.

Another example of the ventilation device includes a body having an air passage for communicating indoors and outdoors, and an opening and closing flap for opening and closing the air passage, as disclosed in Korean Utility Model Registration No. 384769. A ventilation grill having a first air entrance to the interior and a second air entrance to the outdoors and having a plurality of ventilation holes provided at the second air entrance; Rainwater inflow prevention plates installed on an outer surface of the ventilation grill to prevent rainwater from entering the ventilation holes; And a filter installed on the air passage so as to filter the air flowing into the room from the outside.

The conventional window frame ventilator of such a configuration has a useful function to block contaminants contained in outdoor air and to prevent rainwater from entering the room.

In addition, another example of the existing ventilation device is disclosed in the Korean Utility Model Application No. 2007-0003556 "ventilator for the window frame" that the applicant has previously filed, as shown in Figures 1 and 2, the window frame (S) ) Is installed in the through hole (H) between the window glass (G), an air passage (150) is formed therein, an outer vent (111) communicating with the air passage is formed on the outer wall (110), and the inner wall (130) A main body 100 having a plurality of internal ventilation holes 131 communicating with the air passages; An opening and closing flap 190 for adjusting an opening degree of the air passage by pivoting an upper end of the air passage; A filter 170 disposed in a region including the inner ventilation holes 131 of the outer surface of the inner wall 130; The upper and lower ends are detachably coupled to the inner wall while supporting the filter 170, and the grill 180 having a plurality of vent holes 181 is formed.

The first coupling groove 123 is formed in the indoor side of the upper end portion 120 of the main body 100 extending from the upper end of the outer wall 110 of the main body 100 to the interior side, and the inner wall 130 in the first coupling groove 123. ) Is fitted on top.

In addition, the grille has upper coupling ribs 182 having an end bent upward to be inserted into the third coupling groove 124 and lower coupling ribs 183 having an end bent downward to be inserted into the fourth coupling groove 144. do.

However, the conventional window frame ventilator has only the opening or closing function of the opening and closing flap, there is a disadvantage that can not control the flow rate of air flowing from the outdoor to the indoor side.

In addition, in addition to the complex structure for the opening and closing operation of the opening and closing flap on the connection structure of the opening and closing flap, accurate closing and opening operation is achieved only when a modest opening and closing operation.

In particular, when the closing flap is closed, the bottom of the flap must be kept in close contact with the inner wall so that the outdoor and the indoors can be cut off. For this purpose, a separate part such as a soft part is coupled to the lower end of the flap to contact the inner wall. Although there is an improvement in the properties, this has the disadvantage that the production cost for manufacturing a separate component is increased, the assembly labor is increased.

In addition, although it is necessary to adjust the amount of air introduced into the room by adjusting the opening degree of the opening and closing flap on a typhoon or windy day, conventionally, there was a problem that cannot control the air flow rate sucked in stages.
